Aseptic medical instrument packaging with supporting peelable flaps

ABSTRACT

An aseptic medical instrument packaging has supporting peelable flaps by adding a material playing a supporting role which is harder than the rest of an extending part outside a sealing edge of a peeling side of the packaging, or adopting a material which is harder than the rest of an extending part outside a sealing edge of the peeling side of the packaging. A groove is carved in a junction between an outer edge of a sealing edge of a peeling side of the packaging. The material playing the supporting role comprises hard plastic, metal and paper. A soft cover of the packaging is prevented from being curled inwardly in the process of peeling open the packaging; and when one or two peeling sides exist, the degree of differentiation the peeling side will be increased, such that medical staff can conveniently find the peeling side.

TECHNICAL FIELD

The present invention belongs to the field of equipment packaging, inparticular, to an aseptic medical instrument packaging with supportingpeelable flaps.

BACKGROUND ART

Many clinically used articles need an aseptic packaging, for example,aseptic gloves, aseptic gauze, plaster, etc. The article 5.1.9c of thefirst part of Packaging for Terminally Sterilized medical instruments ofISO 11607-2006 which is applied at present prescribes that the peelingcharacteristics shall be continuous and homogenous, without delaminationor tearing of the material that can affect aseptic opening andpresentation. Article 7.3.5 of the Packaging for Terminally SterilizedMedical Instruments of GB/T 19633-2005 prescribes that inpackage-peeling, fiber falling and cracking or breaking off of thepackaging material shall be in a specified limitation of a manufacturerto ensure no influence on the use of medical instruments. However, thesestandards, including pharmaceutical Industry Standards YY/T 0698, do notprescribe an inward curling degree of the peeling side of the packagingfor the terminally sterilized medical instruments when peeled-open. Atpresent, there are many types of medical aseptic packaging, for example,a pre-formed rigid tray is provided with a die-cut lid, flexible peelpouch, sterilization bag, header bag, form/fill/seal (FFS) andfour-side-sealing (4SS) process, etc., (appendix A3 of the first part ofISO11607-2006), and one or both of the upper packaging surface and lowerpackaging surface of the packaging is usually soft. These asepticpackaging are provided with a peeling side/edge, i.e., an extending part(non-aseptic, a gripper part) outside the sealing edge that is widerthan the other three sides. Of course, there are packaging with multiplepeeling sides. In clinical practice, an operator peels the asepticpackaging, the operation standard requires that the peel-open flap ispeeled while two faces (both soft) or one face (soft) of the packagingis turned outwardly and curled. In fact, when the peelable flap of theaseptic packaging is longer and cannot be grasped by the hands or theoperator peels the package in a hasty manner, due to the influence ofthe non-peeled parts at two adjacent sides of the peelable flap, thepart not grasped on the soft cover is turned inwardly and curled, andthe germ-carrying extending part outside the sealing edge contacts withand contaminates contents, thereby increasing an infection risk.Further, damage from sealing fiber and scrap falling off of thepackaging can lead to contamination of the contents. Therefore, there isa need for a controllable soft cover peeling direction of the packagingfor aseptic medical instruments.

SUMMARY OF THE INVENTION

Aiming at the defects of the prior standards and prior art, the presentinvention provides “a controllable soft cover peeling direction of thepackaging for aseptic medical instruments”, the present invention alsoprovides an aseptic medical instrument packaging with supportingpeelable flaps.

The aseptic medical instrument packaging with supporting peelable flapsprovides the supporting peelable flaps by adding a supporting materialwhich is harder than the rest of an extending part of a supportingpeelable flap outside a sealing edge of the peeling side of thepackaging or adopting a material which is harder than the rest of theextending part of the supporting peelable flap outside a sealing edge ofthe peeling side of the packaging; the supporting material compriseshard plastic, metal and paper; the supporting peelable flap plays asupporting role like that of a flagpole when the packaging is peeled, toguide the soft cover of the packaging to be turned and curled toward adesired direction.

The hard plastic is phenolic plastic, polyurethane plastic, epoxyplastic, unsaturated polyester plastic, furan plastics, or plastic madeof organic silicon resin, propenyl resin or modified resin.

The corners of the material playing a supporting role, which is harderthan the rest of and added to the extending part outside a sealing edgeof the peeling side of the packaging are passivated to avoid the damageof the packaging in a storage and transportation process.

The corners of the material playing a supporting role, which is harderthan the rest of and adopted on the extending part outside a sealingedge of the peeling side of the packaging are passivated to avoid thedamage of the packaging in a storage and transportation process.

The metal is aluminum, steel, iron, platinum or alloy.

A groove is carved in the junction between the outer edge of the sealingedge of the peeling side of the packaging and the extending part tofacilitate peeling.

Beneficial effects: 1, the supporting peelable flap plays a supportingrole like that of a flagpole when the packaging is peeled, and the softcover of the packaging is prevented from being curled inwardly tocontaminate the contents; 2, when there are only one or two peelableflaps, the degree of differentiation of the peeling side will beincreased, such that medical staff can conveniently find the peelingside; 3, the present invention resolves the defects of the existingstandards, and puts forwards the new concept of “a controllable softcover peeling direction of the packaging for the aseptic medicalinstruments”, and lays a foundation for our country to obtain certainrights to speak in the high end field of establishment of internationalstandards of packaging for terminally sterilized medical instruments.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1, FIG. 2 and FIG. 3, show an aseptic medical instrument packagingwith supporting peelable flaps, the aseptic medical instrument packagingwith supporting peelable flaps plays a supporting role by adding amaterial 3 which is harder than the rest of the extending part 2 outsidea sealing edge of the peeling side of the packaging 1 or adopting amaterial which is harder than the rest of the extending part 2 outside asealing edge of the peeling side of the packaging; the material playingthe supporting role comprises hard plastic, metal and paper.

The hard plastic is phenolic plastic, polyurethane plastic, epoxyplastic, unsaturated polyester plastic, furan plastics, or plastic madeof organic silicon resin, propenyl resin or modified resin.

The corners of the material playing a supporting role, which is harderthan the rest of and added to the extending part outside a sealing edgeof the peeling side of the packaging are passivated to avoid the damageof the packaging in a storage and transportation process.

The corners of the material playing a supporting role, which is harderthan the rest of and adopted on the extending part outside a sealingedge of the peeling side of the packaging are passivated to avoid thedamage of the packaging in a storage and transportation process.
